4 Claims.

This invention relates to distributing means for coarse aggregates, andit is primarily an object of the invention to provide a means of this.kind for use in stone quarries or the like and ing and the coarse,separating from the fine,: rolls to the edges of the storage place.While the aggregate may be properly graded as it leaves the screen, yetunder this action just mentioned there is that segregation which resultsin an uneven distribution of the aggregate at the storage place. It isan object of the invention to provide means to eliminate thisdisadvantage.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved dis-'tributing means for coarse aggregates whereby certain importantadvantages are attained, as will be hereinafter more fully set forth.

In order that my invention may be better understood, I will now proceedto describe the same with reference to the accompanying draw ings,wherein:

Figure 1 is a fragmentary view illustrating a distributing means forcoarse aggregates constructed in accordance with an embodiment of myinvention.

Figure 2 is a detailed sectonal vew taken on the line 2-2 of Figure 1.

Figure 3 is a sectional view taken substantially on the line 3-3 ofFigure 2.

Figure 4 is a view similar to Figure 1 but illustrating anotherembodiment of my invention.

Figure 5 is a sectional view on the line 5-5 of Figure 4, and

Figure 6 is a sectional view on the line 6--6 of Figure 5.

As illustrated in the accompanying drawings,

B denotes a storage bin ,or other place of stor beams l.

depending spout S substantially vertically disposed.

As illustrated in the accompanying drawings, the upper open end of thebin B has disposed thereover the spaced parallel beams l which havesupported therebetween for rocking movement a distributing apron orchute D. As is clearly illustrated in Figure 2 of the drawings, thisapron or chute D is elongated and fiat, and extending outwardly andlaterally from the opposite sides thereof and preferably at a point'above its longitudinal center are the trunnions 2 which are rotatablydisposed through the beams l.

As is illustrated in Figure 1 of the drawings, it is to be pointed outthat the mounting for the apron or chute D as aiforded by the trunnions2 is directlybelow and centrally of the spout S. As illustrated inFigure 2, the upper end of the apron D is of a width slightly in excessof the discharge end of the spout S and extends slightly beyond oppositesides thereof while the apron or chute D from its upper end toward itslower end increases in width.

One of the trunnions 2 extends through a slot 3 disposed lengthwise of acrank arm 4, whereby the throw of the crank arm may. be selectivelyadjusted as required within the limits of the slot 3. The crank arm 4 isheld in desired adjustment with respect to the coacting trunnion 2 bythe conventional holding and clamping nuts 5 threaded upon the trunnion2 at opposite sides of the crank arm. By 'endwise adjustment of thecrank arm 4, it is believed to be obvious that the extent of rocking ofthe apron or chute D may be regulated as the requirements of practicemay prefer. v

The crank arm 4 adjacent to'an end thereof carries a laterally disposedcrank pin 6 with which is operatively engaged an end portion of a pitmanI which, in turn, is operatively en gaged, as at 8, with an operatingwheel 9 herein disclosed as rotatably carried by one of the This wheel 9is adapted to be operatively engaged with any suitable source of power.

It is to be stated at this time that the spe- .cific means for rockingthe apron or chute D forms no part of the present invention other thanthe provision of means whereby regulation may be had of the extent ofrocking movement of the apron or chute D and that such rocking movementof the apron or chute D is substantially equidistant 'to opposite sidesof the vertical plane of the trunnions 2.

Suitably secured to the oppositeflat faces of the apron or chute D arethe outstanding elongated flanges ID, with the flanges ID at one' sideof the transverse center of the apron or chute D diverging downwardlywith respect to the flanges ID at the opposite side of the transversecenter of the apron or chute D and with the flanges ill-at each side ofsuch transverse center being disposed on downward and outward inclines,with the lower ends of said flanges V I terminating a material distanceinwardly of and forth across the path of flow of the material asdelivered from the spout S, with the result that the aggregate will beevenly distributed both lengthwise and transversely within the binorother place of storage, the distribution in one direction resulting fromthe rocking or oscillating movement of the apron or chute D while thedistribution in a direction transverse to such rocking movement toopposite sides of ,the apron or chute D will be effected by the flangesl0 and which flanges serve to separate the aggregate as it flows overeither of the faces of the apron or chute D into separate streams.

By having the flanges Ill terminate a materia1 distance inwardly of thelower or discharge end of the apron or chute D, a slight spreading ofthe aggregate is permitted as the same passes beyond the lower ends ofthe flanges Ill before the aggregate passes beyond the lower ordischarge end a of the apron or chute D. This spreading eliminatesthe-discharge of the aggregate from the apron or chute D in a mannerwhich would result in the forming of surface ridges on the pile or heapwithin the bin B or other place of storage.

In the embodiment of the invention as illustrated in Figures 4, and 6 ofthe drawings, the material or aggregate discharging from the dependingspout A, of the chute or trough E de-- livers within a tubular orchute-like distributing member M. This member M is flat and open at itsopposite ends and gradually increases in width from substantially itsupper end to its lower end, as illustrated in Figure 5.

The member M is shallow and has its side walls I I provided at theirupper ends or at the smaller end of the member M with the parallelextensions l2 between which the depending spout A is received and towhich spout A the extensions l2 are pivotally connected, as at M,whereby the member M is supported for rocking movement below the spoutA.It will also be noted that the mounting I4 is centrally of the spout Aso that the member M can be caused to rock-or swing forwardly andrearwardly of the spout A to assure the desired eifective distributionof the aggregate within the bin F.

The front and rear walls l5 of the member M at the upper or smaller endof said member are provided with the upstanding and outwardly curvedextension plates l8 which extend upwardly and beyond the lower ordischarge end of the spout A but in relatively close proximity theretoto assure the proper delivery of the material or aggregate from thespout A into the upper end of the member M;

The space between the walls l5 of the member I M have interposedtherebetween and suitably secured thereto the members or flanges ll.These flanges or members ll at opposite sides of the I transverse centerof the member M are arranged in downward divergence so that as thematerial or aggregate passes down through the member M, such material oraggregate will be evenly distributed as it leaves the member M withinthe bin F or other place of storage.

The member M is to be rocked or oscillated to substantially equaldistances at opposite sides of v the vertical center occupied by thepivotal mounting l4. As herein disclosed, one of the side walls I I hasfixed thereto at a desired point therealong an outstanding laterallydirected bracket ill withwhich is operatively connected, as at I9, anend portion of a rigid link or pitman 20 which, in

turn, is operatively connected, as at 2|, with a driven member 22 hereindisclosed as rotatably carried by a beam 22 supported above the bin F.

From the foregoing description it is thought to be obvious that adistributing means for coarse aggregates constructed in accordancewithmy invention is particularly well adapted for use by reason of theconvenience and facility with which it may be assembled and operated.

What I claim is:

l.-A means for controlling the segregation of a vertically dropping flowof aggregates, comprising an elongated flat body of greater width at oneend than at the other, means for pivotally supporting said 'body atopposite longitudinal edges for rocking movement across the said flow,

said means being disposed adjacent the narrower end of the body and therocking axis extending across the body inwardly from the adjacent endedge and being disposed in the center of the flow ,whereby theportion ofthe body lying above the .axis swings tova position across the flow tointercept the entire flow, and means for rocking the body on said axis.

2. A means for controlling the segregation of aggregates as set forth inclaim 1, with means extending lengthwise of the opposite faces of thebody for effecting movement of the aggregates laterally toward thelongitudinal edges of the body.

3. 'A means for controlling the segregation of aggregates as set forthin claim 1 with a plurality of ribs secured to each of the side faces ofthe body and extending lengthwise thereof, the ribs upon each face andat one side of the longitudinal center of the body being angularlydirected oppositely to the ribs upon'the opposite side of thelongitudinal center whereby the aggregate flowing across the faces ofthe body will be caused to flow off of the wider end of the body towardthe longitudinal edges.

4. A means for controlling the segregation of aggregates as set forth inclaim 1 with a plurality of ribs secured to each of the side faces ofthe body and extending lengthwise thereof, the ribs upon each face andat one side of the longitudinal center of the body being angularlydirected oppositely to the ribs upon the opposite side of thelongitudinal center whereby the aggregates flowing across the faces ofthe body will be caused to flow off of the wider end of the body towardthe longitudinal edges, said ribs terminating short of the widertransverse edge of the body whereby to prevent deposition of theaggregate in ridges.
